Will Farrel is funny, and the spoof is well done, but truthfully I am tired of this sort of message. Fun is made about people who question our role in and what our response should be to global warming as having no facts to back them up. This is demonstrated not with facts, but with mocking or demonizing those who have this view. But this issue is, contrary to popular opinion, far from settled in the scientific community.
